Post by thread:f877 + usart + interrupt = headache

a plea for help i'm currently working on a dmx512 decoder the problem i'm having is not being able to get the 2 tasks to run together a interrupt driven loop every 15usec to look after the analogue section and the main body of the program reading data at 250kbaud currently i can either have the analogue section running with no data being thrown at the device or i can have data and the analogue wont enter the interrupt routine the rcif on the rx section is just polled to make life easier i think can the pic run the usart independantly or does the pic devote all its power to the usart when receiving any help appreciated many thanks chris

It may give you some ideas on how I received the DMX signal.
